What is the equation of a line perpendicular to y=2.5x+5

Sauron [17]

Answer:

y = -0.4 + c

Step-by-step explanation:

y = mx + c (original form)

m ⊥ - 1/m

2.5 = 25/10

25/10 ⊥ -10/25

-10/25 = -0.4

y = -0.4x + c

An aquarium holds 33.75 gallons of water. it has a length of 2 feet and a height of 1.5 feet. What is the volume of the aquarium

I am Lyosha [343]

Assuming that the aquarium is rectangular, the formula to work out the volume would be
V = L x H x D
Considering that 1 gallon = 231 inches³
Multiply both by 33.75 to get the total number of inches³ (volume)
231 x 33.75 = 7796.25 inches³

If you also want the depth, read on...

Also, there are 12 inches in one foot
Length = 2 x 12 = 24 inches
Height = 1.5 x 12 = 18 inches

Now we can fill in the information we know

7796.25 = 24 x 18 x D
To work out D, we divide the volume by the values we know
7796.25 / 18 = 433.125
433.125 / 24 = 18.046875 inches
18.046875 / 12 = 1.50390625 feet
To the nearest 2d.p. ≈ 1.5 feet

Calculate the axis of symmetry in the equation Y = (x+1) (x-4)

algol [13]

Answer:

Every parabola has a turning point called the axis of symmetry,so for this question you just have to find the turning points

x turning point= -b/2a,and the y turning point is gotten by replacing the value of x in the equation

y=(x+1)(x-4)

=x^2-3x-4

a is 1,b is -3 and c is -4

x= -(-3)/2(1)

=1.5

and y=x^2-3x-4

=1.5^2-3(1.5)-4

= -6.25

therefore the axis of symmetry is (1.5,-6.25)

I hope this helps
